A ballast water treatment method includes: a step of supplying a sterilizing component to a ballast pipe while taking ballast water into a ballast tank through the ballast pipe; a first measurement step of measuring the concentration of the sterilizing component in the ballast water after the sterilizing component is supplied; a circulation step of returning the ballast water stored in the ballast tank to the ballast pipe through a circulation pipe; a second measurement step of measuring the concentration of the sterilizing component contained in the ballast water returned to the ballast pipe; and a step of supplying the sterilizing component to the ballast pipe 2 when the concentration of the sterilizing component measured in the second measurement step is less than 0.2 times the concentration of the sterilizing component measured in the first measurement step. In the first supply step, the sterilizing component is supplied to the ballast pipe 2 such that the concentration of the sterilizing component measured in the first measurement step becomes 6 mg/L or more.

One aspect of the present invention provides a method of treating ballast water, which includes: a first step of transporting a raw material from a first base to a second base where a vessel is configured to be anchored; a second step of inputting the raw material into an on-site treatment agent manufacturing facility located at the second base to manufacture a treatment agent; and a third step of supplying the treatment agent to the vessel anchored at the second base and treating ballast water using the treatment agent.

A device for capturing in-port ship exhaust gases is designed to be connected to a ship, when the ship has at least one funnel that serves as an outlet for exhaust gases. The device includes at least one collection device, including a hood designed to connect to the funnel at the exhaust outlet so as to collect the exhaust gases coming out of the funnel, a handling unit designed to move the collection device and position it at the exhaust outlet, a first constraint configured to interconnect or disconnect the collection device and the handling unit by command so as to create a handling configuration in which the collection device and the handling unit are interconnected by the first constraint and can be moved as one, and a collection configuration in which the collection device collects the exhaust gases and the connection achieved by the first constraint is released, and a second constraint configured to exert a magnetic attraction force, by command, intended to put the first constraint into the handling configuration.

A water treatment system and a ballast water treatment method. A ballast water treatment system according to an embodiment of the present invention comprises: a first ballast water supply pipe for receiving a supply of ballast water from a first sea chest positioned in a non-explosion-proof area of a ship; an electrolytic bath for electrolyzing the ballast water supplied from the first ballast water supply pipe; a second ballast water supply pipe for receiving a supply of ballast water from a second sea chest, which is positioned in an explosion-proof area of the ship, and supplying the ballast water to a ballast tank of the ship; a filter provided to the second ballast water supply pipe so as to filter the ballast water passing through the second ballast water supply pipe; and a third ballast water supply pipe connected to the second ballast water supply pipe so as to supply the ballast water, which has been electrolyzed from the electrolytic bath, to the ballast water which has passed through the filter.
